Following a difficult Fourth of July week 2019 for blood and platelet donations and ongoing challenges finding new blood donors, the American Red Cross now faces a blood shortage and has issued an emergency call for eligible individuals of all blood types to give now and prevent delays in medical care. About 450 fewer blood drives were organized by businesses and other community groups last week than during a typical week as people across the country celebrated the holiday with activities and travel. This led to about 17,000 fewer blood donations than needed for patients in a single week, causing the Red Cross to now have less than a three-day supply of most blood types available – and less than a two-day supply of type O blood – for patients. At least a five-day supply is desired. In June, the Red Cross launched the Missing Types campaign to encourage donors – especially new donors and those who have not donated in the past years – to give blood or platelets during the challenging summer months. Through the campaign, the letters A, B and O – letters that make up the main blood groups – disappeared from popular brands to symbolize what happens when blood goes missing from hospital shelves during blood shortages. Despite an encouraging response to the campaign, blood donations still fell short of expectations in June, resulting in more than 24,000 fewer donations than needed and causing a significant draw down of the Red Cross blood supply. Donors of all blood types, especially type O, are urged to make an appointment to donate using the Blood Donor App, at RedCrossBlood.org or by calling 1-800-RED CROSS (1-800-733-2767). Donation appointments and completion of a RapidPass online health history questionnaire are encouraged to help reduce the time it takes to donate.
